WINDOW SCREEN.

Specification of Letters Patent.

Patented July 11,1922.

Application filed September 7, 1920. Serial No. 408,654.

To aZZ whom it may concern.

Be it known that ISAAC lV. CHERRY, a citizen of the United States, residing at Pensacola, in the county of Eseambia andState of Florida, has invented certain new and useful Improvements in \Vindow Screens, of which the following is a specification, referenec being bad to the accompanying drawings. I

This invention relates to window screens and has for its object to provide a screen which may be raised similar to awindow sash and maintained in its raised position indefinitely without the use of props.

Another object is to provide a screen of this character wherein the frame is composed of two frame members adapted to coincide with each other, the sides of said members being wider than the upper and lower portions, a portion of said sides being extended in angular relation thereto and formed into a tongue for sliding movement between guides carried by the window frame.

With the above and other objects in view, the invention consists in the improved c0nstruction and arrangement of parts to be hereinafter more particularly described fully claimed and illustrated in the accompanying drawings, in which Figure 1 is a vertical elevation of a window sash showing the screen applied,

Figure 2 is a fragmentary vertical elevation and sectional view of a window sash and screen. and

Figure 3 is a transverse sectional view of the window sash and screen.

Referring to the drawings. designates a window frame. and B the window shutters carried by the frame, said shutters having adjustable slats C adjusted by means of the rods D. The above mentioned structure forms no part of the invention.

In order to provide a screen adapted for use with the window frame using this type of shutter, I provide a novel frame structure consisting of two frame members 5 and 6, said members are in vertical alignment with each other. Each member in eludes an upper rail 7. a lower rail 8 and an intermediate rail 9, the rail 9 may be formed integral with the frame member or attached separately. The side rails 10 of the frame member are relatively wider than the upper,

lower and intermediate rails, the outer or-.

tion of said side rails being extended in right angular relation to said rails to provide a flange 11, the intermediate portion of said flange being formed with a longitudinally extending crimp to provide a tongue 12, said tongue being disposed in spaced relation to the main portion of the side rails and. the edge thereof so as'to form two shoulders 13 and l t, the purpose of which will be hereinafterdescribedQ Each of the rails T, 8 and 9 are formed with a plurality of eoncavo eonvex depressions 15 in spaced relation to each other laterally of the framemember, the depressions'in each rail registering with the depressions" in the adjacent rail. A sheet of wire fabric 16 is disposed between the frame members 6 and 7' and'is extended over the convex surface of the depressions 15 into the frame members 5 and into the'concav'e portion ofthe depressions in the frame mem her 6. In this way the depressionsof the frame members 5 and 6 serve as clamps and at the same time cause the screen fabric to form a channel 17 vertically of the screen frame, said channels being disposed in spaced parallel relation to each other. These chan nels and depressions are formed to suit the construction of the adjusting rods D and are intended to re eive the same when the shutters are closed. The wire fabric 16 is secured between the frame members 5 and '6 by suitable fastening means 18 such as rivets which also serve to connect the frame members to each other and provide a substantial structure.

To permit the screen to be raised and lowered with ease and rapidity, I provide a pair of guide members 19, each of said members being substantially U-shaped in cross section and adapted to be secured to the stiles of the window frame. These guide members are intended to receive the tongue 12 of the screen frame, the edges 20 of said guides being disposed closely adjacent the shoulders 13 and M. In this way, the crimp or tongue guides the frame in its sliding movement while the edges 20 maintain the screen in the proper position and limit lateral movement thereof so that danger of the screen being canted or jammed is eliminated.

An expansible and retractable member 21 is secured at its end 22 to the upper por tion of the window frame A. This member extends over one of the rollers pivot ally mounted in the upper corners of the frame. One of these members is provided for each side of the frame and is intended to extend over the adjacent roller 23, through the guide member 19 and is secured at its end 24 to the top portion of the sidev member 10. By this means the expansible and retractable member serves the purpose of a sash Weight to permit the screen to be readily raised. It is impossible for the member 21 to become entangled with the other parts of the frame as it is fully protected by the guide 19. The lower rail 8 of each of the frame members 5 and6 is provided with an extension 25 in which is mounted alatch 26 having a head on one end thereof, a retractable spring surrounding the-latch, one end of said spring being secured to the head and the opposite end to the extension '25, said spring being adapted to normally urge the latch member outwardly and into an opening 27 formed in the lower portion ofthe window frame to lock the screen in place. The rail 8 of'the members 5 and 6 has its intermediate portion extended inwardly to provide an opening 28 through which the fastening means E of the shutters may be passed to lock the shutters.

From the foregoing it will be readily seen that this invention provides a novel form of window screen structure which permits the screen to be raised and lowered similar to a sashand maintained it in its raised position without the use of props. In addition to this, the adjusting rods D of the shutters may be conveniently disposed within the channel 17 to permit the blinds to be closed without removing the screen.

Another important feature is that the frame said tongue being "slidable in the guides, and

means carried by the free edges of said flanges for holdin'gthe screen in various positions i f Y v v a In testimony whereof I hereunto affix my signature. I
